Regarded widely as the world’s ugliest animal, the blobfish (Psychrolutes marcidus) resides in the deep waters off the coast of Australia and Tasmania. Due to its gelatinous body optimized for a life of extreme pressure, this fish appears comically deformed and flabby when brought to the surface. Despite its looks, the blobfish has become an intriguing symbol of deep-sea creatures’ adaptive evolution.
